LeBron James undecided on jersey No. 6 or 23

He turned to social media Friday to help him choose which number he'll wear next season. James wrote "6 or 23...." on his Twitter account and posted photos on Instagram of him wearing No. 6 and No. 23 wine and gold Cavs jerseys.

James wore No. 6 during his four seasons with Miami and also on the U.S. Olympic team. He used No. 23 in high school and during seven seasons in Cleveland.

James has had the top-selling jersey in the NBA six times during his career.

His return to Cleveland has given the city a boost, and the Cavs quickly sold out their seasons tickets in the hours after his announcement.

James signed a two-year, $42.1 million contract last week.
